Answer 1

A

Answer 2

8.9% x 3.72 = .33108
.33108+3.72= 4.05

Answer 3

Finding the percent of change is using the ratio of the amount of change to the original amount. The increased amount is really the percent of increase.

$4.05-$3.72 = $.33

Then you divide by the Original amount.

$.33/$3.72 = .0887

Multiply by 100 to find the percentage

.0887 = 8.87% which rounds to 8.9%

Answer 4

Or that way works
